【问题描述】：

我想在 GoogleMap 中为地标设置填充颜色，但它不起作用。我使用来自fill polygons in google map/earth 的 KML 我的结果是： http://i.imgur.com/ed27B0I.jpg?1

我的代码是：

KmlLayer kmlLayer = new KmlLayer(googleMap,R.raw.test,getActivity().getApplication());
kmlLayer.addLayerToMap();

KML 文件是：

标签： android google-maps kml

【解决方案1】：

您是否浏览过此受支持元素列表？ https://developers.google.com/kml/documentation/kmlelementsinmaps

我看到您使用了一些不受支持的元素（例如高度模式）。从理论上讲，如果您这样做，它应该会静默失败，但似乎它可能会影响整体结果（请参阅此issue 的答案）。

我也认为这就是@JeremyA1 的答案可能不起作用的原因，因为 StyleMap 也不支持。

无论如何，请告诉我们您是如何解决的，因为这将非常有帮助。

首先，您需要缺少的标签。试试这个更新的代码

【解决方案3】：

从此代码中删除颜色模式、填充和轮廓：

<PolyStyle>
    <color>7f0000ff</color>
    <colorMode>normal</colorMode>
    <fill>1</fill>
    <outline>1</outline>
  </PolyStyle>

应该是这样的：

<PolyStyle>
    <color>7f0000ff</color>
  </PolyStyle>

结果如下：
